TL;DR: This study is a review of the recent literature on the use of natural and modified lignocellulosic residues for Cr adsorption and finds that many by-products of agriculture have proved to be suitable low cost adsorbents for Cr(VI) and Cr(III) removal from water.
782 citations
TL;DR: This review reports the recent developments in the Hg(II) removal in waste water treatment, using chitosan and its derivatives in order to provide useful information about the different technologies.
430 citations
TL;DR: In this paper, chemical analyses of dissolved silica in the shallow groundwater of the lower part of the Salado River drainage basin indicate that silica values averaged 60ppm, and the sources of amorphous silica are volcanic glass shards and biogenic silica derived from plant (silicophytoliths, diatom frustules) or animal remains also present in the Pampean loess.

TL;DR: In this article, chemical analyses of major ions were performed in some of the pampasic ponds in the lower stream bed of Salado River drainage basin, where total dissolved solids had a mean value of 1341 mg/l, where sodium was the most abundant of the cations.
Abstract: Chemical analyses of major ions were performed in some of the pampasic ponds in the lower stream bed of Salado River drainage basin. Results indicated that total dissolved solids had a mean value of 1341 mg/l, where sodium was the most abundant of the cations (80.2%) and chloride (44.2%) and bicarbonate (37.4%) were the predominant anions. Saturation index showed oversaturation with respect to calcite and dolomite. Since groundwater is the main source of surface water, high sodium concentration in the ponds may be explained by a cation exchange process in the loessic sediments of the basin where calcium is replaced by sodium.

TL;DR: In this article, the authors provide a sketch about treatment technologies followed by their heavy metal capture capacity from industrial effluent, the treatment performance, their remediation capacity and probable environmental and health impacts were deliberated in this review article.
Abstract: The controversy related to the environment pollution is increasing in human life and in the eco-system. Especially, the water pollution is growing rapidly due to the wastewater discharge from the industries. The only way to find the new water resource is the reuse of treated wastewater. Several remediation technologies are available which provides a convenience to reuse the reclaimed wastewater. Heavy metals like Zn, Cu, Pb, Ni, Cd, Hg, etc. contributes various environmental problems based on their toxicity. These toxic metals are exposed to human and environment, the accumulation of ions takes place which causes serious health and environmental hazards. Hence, it is a major concern in the environment. Due to this concern, the significance of developing technology for removing heavy metals has been increased. This paper contributes the outline of new literature with two objectives. First, it provides the sketch about treatment technologies followed by their heavy metal capture capacity from industrial effluent. The treatment performance, their remediation capacity and probable environmental and health impacts were deliberated in this review article. Conclusively, this review paper furnishes the information about the important methods incorporated in lab scale studies which are required to identify the feasible and convenient wastewater treatment. Moreover, attempts have been made to confer the emphasis on sequestration of heavy metals from industrial effluent and establish the scientific background for reducing the discharge of heavy metals into the environment.
